<p>Provided is an adhesive that satisfies all the performances on corrosiveness of metal such as ITO, whitening of heat and humidity, and heat-resistant effervescent, and has good workability. [Solution] An adhesive characterized by containing an acrylic polymer that is obtained by copolymerizing the following (a1) to (a3), (a1) 20 to 99.8% by mass of alkoxyalkyl(meth)acrylate, (a2) 0.1 to 10% by mass of monomers containing crosslinkable functional groups, and (a3) 0.1 to 5% by mass of hydrogen bond monomers, and has a weight-average molecular weight of 50,000 to 400,000 and substantially no carboxyl group-containing monomer, and (b) an isocyanate-based crosslinking agent; and a pressure-sensitive adhesive sheet characterized by arranging a pressure-sensitive adhesive layer that is formed on at least one surface of a support by the aforementioned adhesive.</p> |
